Undo history and branching is unlimited
Digital Performer records an unlimited number of
branches and actions in the Undo History window.
How much it can remember is limited only by the
amount of RAM and disk space in your computer.
Pruning preferences
The undo history has the potential to take up large
amounts of memory and disk space, depending on
the type of work you are doing. In addition, you
may find that you rarely go back in time more than,
say, about an hour as you work. For circumstances
like these, Digital Performer can discard — or
“prune” — branches according to rules that you
specify and that accommodate your work style and
needs. Click the Pruning Preferences button to
open these preferences as shown below:
Figure 47-7: Pruning preferences.
The Prune entries when there are more than _
entries option lets you limit the number of undo
history entries to any number that you specify from
the menu provided. When an undo entry moves
back in the history further than this limit, it is
permanently discarded.
The Prune Entries taking up more than option
applies to all actions, both on the main trunk and
in all branches. This option can be useful during
recording sessions, in which you are likely to
generate and discard large amounts of audio data.
But if you are the type of person who often searches
back for takes you recorded way back at the
beginning of your sessions, use this option with
caution!
The Prune Entries on branches option only applies
to actions that are in branches and are therefore
undone. In other words, they are actions that are
not on the path that you took to get to the project in
its current state (the main trunk). Often, these
types of actions are much less likely to be revisited,
so you can be more aggressive about pruning them.
The last option, When Audio recording try to
keep…, forces the undo history to flush items when
disk space gets low. It starts with actions farthest
back in the history and works its way forward as
needed. What you choose here depends largely on
how much disk space your system provides, and
the manner in which you record.
Undo History for POLAR sessions
POLAR sessions have their own Undo History
window, which you can open by clicking the
History button in the POLAR window itself.
POLAR session Undo Histories work the same way
as project Undo Histories, except that they are not
saved. Instead, they are discarded when the
POLAR session is closed.
Undo History for audio files
Each audio file has its own Undo History window.
To op e n i t, c l ick t he Open Undo History button in
the audio file’s Waveform Editor.
